Change agency_type to a Rails enum

[dorner]

Summary

There are a number of tests that check PartnerProfile#agency_type against a string "Other". Some other tests check the value in an array instead:

Partner::AGENCY_TYPES['OTHER']

This seems to be hiding a hidden issue, which is that this field really should be an enum. We don't need to go all the way to defining a Postgres enum; we can just turn the field into a Rails enum as documented here.

Things to consider

A bonus to this would be moving the AGENCY_TYPES map from the Partner class to the PartnerProfile class, as that's where it's actually used.

Criteria for Completion

• [] Agency type is a Rails enum.
• Specs are updated to query e.g. profile.other? instead of checking against any specific string value.
• All other functionality still works as expected.

I'd like to pick this issue up.

Go for it!

It looks like we're currently storing the agency type description string in the database (not the code). Do we want, as part of this PR, a migration to convert agency types from, for example, Government Agency/Affiliate to GOVT?

[dorner]

Hmm... that's a good question. I think it's definitely a better approach than storing the full string. We'd have to be very careful about the rollout, though.

I think we'd have to do something like allowing both long and short values in the enum hash, then doing the migration, then removing the long values from the hash.

We're just waiting on a data cleanup (#4261) before we move forward on this one.

Automatically unassigned after 7 days of inactivity.

NDBN sent me back some stuff, but I need to review it -- probably a Monday job at this point.
